And it's also possible with this technique to interact with it, so your actions could change the outcome of the movie.

That's not a movie. That's a game. IMO.

A game is something you're playing the whole time, and that's not the case with a movie. With a movie, there has to be a story that you could watch and experience in 3d in the room you're in, and not on a flat screen, but maybe at certain moments you could also participate by interacting with the movie, so you're not only a spectator anymore, but someone who will actually play a role in the movie, maybe something like this, making choices, but WITH augmented reality

Your choices will have a large influence in how the movie will develop, so you could experience the same movie several times. Wouldn't that be fun... I really don't know if this will ever actually happen, but if it does, that would be very cool imo and it would change the entire process of moviemaking. This all came up in my mind after watching that augmented reality video. Does anyone think this could become reality in the future? http://www.youtube.com/watch?v=aLCUzA6KMEw http://www.ladyofrohan.com/funeralsong.wav
